[0001] This utility model relates to the field of weaving machine technology, specifically a weaving machine with an automatic weft yarn bending structure. Background Art

[0002] A weaving machine is a type of machinery used to manufacture textiles. It forms fabric by interlacing weft threads or yarns together in a specific manner.

[0003] When a knitting machine is working, the weft yarn bending structure is designed to automatically process the weft yarns (horizontal threads) during the knitting process, causing them to form a certain curved shape before entering the fabric. This function is particularly useful for certain types of fabrics, such as those that need to enhance the three-dimensionality of the fabric or to achieve specific fabric structures and effects. However, existing equipment makes it inconvenient to adjust the angle when processing the weft yarns, and the adjustment of the feed position is also relatively complicated. Therefore, we propose a knitting machine with an automatic weft yarn bending structure. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Please see Figures 1-3 This utility model provides a technical solution: a weaving machine with an automatic weft yarn bending structure, including a base 1, an mounting plate 3 fixedly installed on the top of the base 1 by multiple sets of connecting columns 2, two sets of fixing claws 4 fixedly installed on the outside of the base 1, a rotating mechanism 5 provided on the mounting plate 3, a mounting frame 7 fixedly installed on the top of the rotating mechanism 5, a tensioning mechanism 8 for tensioning the weft yarn slidably connected on the mounting frame 7, and an angle adjustment mechanism 9 for adjusting the weft yarn angle provided on the mounting frame 7 and on one side of the tensioning mechanism 8.

[0018] The entire device can be installed and fixed by setting the base 1 and fixing claw 4. Then, the weft yarn to be supplied passes through the tensioning mechanism 8 and the angle adjustment mechanism 9. This setting can use the tensioning mechanism 8 to prevent the weft yarn from being too loose and falling out of the angle adjustment mechanism 9. The angle adjustment mechanism 9 can adjust the vertical angle of the weft yarn, so as to facilitate the adjustment of the weft yarn feeding position. The rotating mechanism 5 can drive the tensioning mechanism 8 and the angle adjustment mechanism 9 to rotate, ensuring that the feeding position can be quickly adjusted when the weft yarn is fed.

[0019] Please see Figure 1 , Figure 2 and Figure 3 The rotating mechanism 5 includes a rotating base 10, a rotating shaft 11, a top plate 12, a first gear disk 13, and a drive motor 14. The top of the mounting plate 3 is rotatably connected to the rotating shaft 11 via the rotating base 10. The top plate 12 is fixedly mounted on the top of the rotating shaft 11. The first gear disk 13 is fixedly mounted on the outside of the rotating shaft 11. The drive motor 14 is fixedly mounted on the bottom of the mounting plate 3. The output end of the drive motor 14 is fixedly connected to a second gear disk 15 that meshes with the first gear disk 13.

[0020] When the tensioning mechanism 8 and the angle adjustment mechanism 9 are rotated, the drive motor 14 operates, and the drive motor 14 drives the second gear disk 15 to rotate. The rotating second gear disk 15 can drive the first gear disk 13, the rotating shaft 11 and the top plate 12 that mesh with it to rotate along the rotating seat 10, so that the tensioning mechanism 8 and the angle adjustment mechanism 9 installed on the top plate 12 can be angled.

[0021] Please see Figure 1 , Figure 2 and Figure 3 The tensioning mechanism 8 includes a limiting sleeve 16, a telescopic rod 17, a first limiting wheel 18, a fixed plate 19, and a spring 20. The limiting sleeve 16 is fixedly installed on the mounting frame 7. The telescopic rod 17 is slidably connected to the limiting sleeve 16. The first limiting wheel 18 is rotatably connected to the telescopic rod 17. The fixed plate 19 is fixedly installed at the bottom of the telescopic rod 17. The spring 20 is fixedly installed at the top of the fixed plate 19 and outside the telescopic rod 17. The top of the spring 20 is fixedly connected to the mounting frame 7.

[0022] The weft yarn that needs to be fed passes through the bottom of the first limiting wheel 18. Due to the self-adjustment of the second limiting wheel 18 and the tension provided by the spring 20, the first limiting wheel 18 can be used to pull the weft yarn downward, thereby ensuring that the weft yarn remains in a taut state.

[0023] Please see Figure 1 , Figure 2 and Figure 3 The angle adjustment mechanism 9 includes a support rod 22, a second limiting wheel 23, a drive cylinder 25, and a mounting base 26. The top of the mounting frame 7 is rotatably connected to the support rod 22 via a first hinge seat 21. The second limiting wheel 23 is rotatably connected to the support rod 22. The top of the mounting frame 7 and located on one side of the first hinge seat 21 is rotatably connected to the drive cylinder 25 via a second hinge seat 24. The mounting base 26 is fixedly installed on one side of the support rod 22. The output end of the drive cylinder 25 is rotatably connected to the mounting base 26 via a third hinge seat 27.

[0024] The weft yarn, after being tensioned by the tensioning mechanism 8, passes above the second limiting wheel 23, thus guiding the weft yarn through the second limiting wheel 23. Subsequently, when the angle of the second limiting wheel 23 needs to be adjusted, the drive cylinder 25 operates, which can push the support rod 22 and the second limiting wheel 23 to rotate along the first hinge seat 21, thereby completing the adjustment of the weft yarn feeding position.

[0025] Please see Figure 1 , Figure 2 and Figure 3 A protective cover 6 is fixedly installed on the top of the mounting plate 3. A limiting groove 28 is opened on the outside of the top plate 12. A limiting ring 29 that fits into the limiting groove 28 is fixedly installed inside the protective cover 6.

[0026] The protective cover 6 can protect the first gear disk 13 and the second gear disk 15, and can be limited by the limiting groove 23 and the limiting ring 29 when the top plate 12 rotates, thereby preventing the top plate 12, the tensioning mechanism 8 and the angle adjustment mechanism 9 from shifting when adjusting their angles.

[0027] Please see Figure 2 The first limiting wheel 18 and the second limiting wheel 23 are both made of stainless steel. The stainless steel material used in the first limiting wheel 18 and the second limiting wheel 23 can avoid weft contamination.

[0028] In use, the entire device is first installed and fixed by setting the base 1 and fixing claw 4. Then, the weft yarn to be supplied passes through the tensioning mechanism 8 and the angle adjustment mechanism 9. This setting allows the tensioning mechanism 8 to prevent the weft yarn from becoming too loose and detaching from the angle adjustment mechanism 9. The angle adjustment mechanism 9 can adjust the vertical angle of the weft yarn, thus facilitating the adjustment of the weft yarn feeding position. The rotating mechanism 5 can drive the tensioning mechanism 8 and the angle adjustment mechanism 9 to rotate, ensuring rapid adjustment of the feeding position when the weft yarn is fed. When the tensioning mechanism 8 and the angle adjustment mechanism 9 are rotating, the drive motor 14 operates, driving the second gear disk 15 to rotate. The rotating second gear disk 15 can drive the first gear disk 13 meshing with it. The rotating shaft 11 and the top plate 12 rotate along the rotating seat 10, which allows the tensioning mechanism 8 and the angle adjustment mechanism 9 mounted on the top plate 12 to be adjusted. The weft yarn to be fed passes through the bottom of the first limiting wheel 18. Due to the self-adjustment of the second limiting wheel 18 and the tension provided by the spring 20, the first limiting wheel 18 can pull the weft yarn downward, thus ensuring that the weft yarn is continuously taut. After being tensioned by the tensioning mechanism 8, the weft yarn passes through the top of the second limiting wheel 23, thus guiding the weft yarn through the second limiting wheel 23. Subsequently, when the angle of the second limiting wheel 23 needs to be adjusted, the drive cylinder 25 operates. The drive cylinder 25 can push the support rod 22 and the second limiting wheel 23 to rotate along the first hinge seat 21, thus completing the adjustment of the weft yarn feeding position.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
